The study was recently published in the journal Research Alzheimer’s & Dementia have found that drinking more than two cups of coffee a day helps older adults reduce their risk of developing more severe dementia, according to the science site. Science Alert.
Accordingly, moderate daily caffeine intake has a positive impact on spinal fluid signs of Alzheimer’s disease.
Scientists from the University of Lille and Paris Cité University in France looked at data from a prospective study evaluating patients with mild cognitive impairment or Alzheimer’s disease over five years.
Their analysis included 263 participants over 70 years old, who received an initial clinical assessment and a detailed survey of their consumption of foods and beverages such as coffee, chocolate, and tea to assess their caffeine intake. their bodies absorb it every day. Participants also had MRI scans and provided blood and cerebrospinal fluid (CSF) samples.
They were divided into 2 groups depending on the amount of caffeine consumed:
Low caffeine consumption group: Includes people who consume less than 216 mg of caffeine per day – equivalent to 1-2 cups of coffee.
High caffeine consumption group: Includes people who consume more than 216 mg of caffeine per day – meaning more than 2 cups – about 3 cups of coffee per day.
The results found that the group consuming more caffeine had a lower risk of mild cognitive impairment – with impaired memory, than the group consuming less caffeine, according to the study. Science Alert.
Specifically, people in the high caffeine consumption group – meaning drinking more than 2 cups of coffee a day, had nearly 2.5 times lower risk of mild cognitive impairment, or Alzheimer’s disease.
Taking a closer look at the proteins in the participants’ cerebrospinal fluid, the authors also discovered significant differences in the proportion and concentration of beta-amyloid forms of protein in the brain – a biomarker of Neurodegenerative disease causes symptoms of Alzheimer’s disease.
Overall, cerebrospinal fluid in people who consumed more caffeine had less beta-amyloid protein.
Thus, the habit of sipping coffee is not only beneficial for all ages but is also especially important for the elderly.
According to studies, ideally you should drink 2-3 cups of coffee a day, but should not drink more than 4 cups.
